Abstract End or intermediate interruption of one or both sides of insulation is effected by selective application of release agent to the area of the conductor to be interrupted before lamination of the conductor between sheets of insulation. Multiple conductor cable is provided by winding conductor from a single supply in a controlled pitch onto a revolving flat mandrel containing sequential bands of release agent and adhesive coated insulation. The outside surfaces of the sheet are similarly covered with said bands to form an assembly which is laminated to provide a sequentially interrupted, flexible conductor cable. The system of the invention provides precision placement of insulation on the conductors, leaving exposed interrupted areas of the conductor in an absolutely clean and undamaged condition.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
25 words
A method according to claim 1, in which the bands of insulation comprises a flexible film of dielectric containing a coating of heat-curable adhesive resin.
Claim 2
Dependent Claim
16 words
A method according to claim 2 in which the dielectric film comprises a cured, thermoset resin.
Claim 3
Dependent Claim
15 words

Claim 4
Dependent Claim
20 words
A method according to claim 4 in which the adhesive resin comprises a B-stage epoxy resin containing a heat-activated catalyst.
Claim 5
Dependent Claim
35 words
A method according to claim 1 in which the outer surfaces of the conductors on each side of the flat mandrel are covered with opposed bands of release material and insulation to form an assembly.
Claim 6
Dependent Claim
28 words
A method according to claim 1 in which the assembly is laminated between rigid pressure plates and at a temperature above the curing temperature of the adhesive resin.
Claim 7
Independent Claim
101 words
A method of forming a flexible, insulated, electrical cable comprising the steps of: applying to each surface of a flat, revolvable mandrel a sheet of solid, laminatible insulation; revolving said mandrel and winding conductor wire from a single supply in a controlled pitch onto said mandrel to form a continuous, tight helix including a layer of spaced, parallel conductor wires on each surface of the mandrel; covering said layers with sheets of laminatible insulation to form an assembly; laminating said assembly; and severing said helix along the turns at one edge of the mandrel to form a flexible, insulated, electrical cable.
Claim 8
Dependent Claim
26 words
A method according to claim 8 in which the sheets of insulation comprise a flexible film of dielectric containing a coating of a heat-curable adhesive resin.
